IMPRQVEMENT IN -WASHING-MACHINES:

Specification forming part of Letters Patent No. 141,562, dated August5, 1873; application filed March 8, 1873.

To all whom it may concern:

Be it known that I, JOHN H. Koosnn, of Pekin, in the county of Tazewelland State of Illinois, have invented certain Improvements inWashing-Machines, of which the following is a specification:

My invention relates to that class of machines in which a verticalrevolving sh aft having arms on its lower end is used to dash theclothes about in a box or body. The invention consists in operating areciprocating rackbar,,which drives the pinion of the vertical shaft, bya hand-lever having its lower end arranged to work in a slotted stud onthe bar.

Figure 1 is a .top plan view of my machine; Fig.2, a transverse verticalsection of the same on the line as a; and Fig. 3, a side elevation ofthe pinion, rack-bar, and hand-lever.

In constructing the machine, I build a body, A, of any suitable size andform, and mount in the top thereof a vertical shaft,B, provided on itslower end with a series of arms, 0, and on its upper end, outside of thebody, with a pinion, D. By the side of the pinion D, and so as to geartherein, I secure a horizontal sliding rack-bar, E, so that when movedback and forth it will turn the pinion, and thereby the shaft B and arms0, first in one direction and then in the other. The rack-bar isprovidedwith a vertically-slotted stud, b, and is moved to and fro by ahand-lever, F, which is pivoted in standards 0, and provided at itslower end with a lateral stud or wrist, d, which works in the slottedstud b of the rack-bar, as shown in Figs. 1 and 3. When the lever ismoved back and forth its lower end slides the rack-bar to and fro, andthe latter, in turn, acting upon the pinion D, causes it, with the shaftB and arms 0, to turn alternately to the right and left. The rack-bar isheld and guided by studs '6 on its under side,which slide in a slottedplate, B, secured to the top of the body,

as shown in Figs. 1 and 2. The plate is also formed with an ear or lug,through which the shaft passes, to form a bearing or support for theshaft. The shaft is also supported by a plate, is, secured to the underside of the top or cover, and by an arm, I, which is secured to the bodyand curved upward to receive the upper end of the shaft, as shown inFig. 2. The lower portion of the hand-lever is cast in one piece, withthe journals or trunnions upon it, and with a socket, m, to receive thewooden portion or handle, which can be at any time attached and placedwithin the body out of the way. In order to reduce the friction thewrist or stud of the hand-lever which works in the slotted stud of therack-baris provided with a roller, as shown in Fig. 3. The arms aresecured to the lower end of the shaft by a metal socket, I, which isscrewed fast to the arms and keyed fast upon the end of the shaft, asshown in Fig.2. The end of the shaft is made square and tapered down,and the socket made of a form to correspond, so that when the key or pinwhich unites them is inserted and driven home it hugs them tightlytogether so as to prevent them from playing or rattling.

Having thus described my invention, what I claim is-- 1 In a washingmachine, the combination of the shaft B provided with the arms 0 andpinion D, the rack-bar E provided with the slotted stud b, and thehand-lever, having its lower end arranged to work in the slotted stud,as shown.
